International Classification:

B41J 2300

US Classification:

347 37, 347 19

Abstract:

A method of positioning an ink jet printhead in a printer includes dividing a bitmap into a plurality of rows of tiles. A subset of the rows of tiles to be printed in a next pass of the printhead is identified. Printable ones of the tiles in the subset of rows are identified. The printable tiles contain printable data. Within each printable tile, a top most location of the printable data and at least one of a left most location of the printable data and a right most location of the printable data are identified. A print medium is advanced in a feed direction until a portion of the print medium corresponding with the top most location of the printable data of at least one printable tile is substantially aligned with a top nozzle of the printhead. The printhead is moved, in a scan direction, directly to a position on the print medium corresponding to one of the left most location of the printable data of at least one printable tile and the right most location of the printable data of at least one printable tile.

US Classification:

358001140

Abstract:

A method for printing an interrupt print job including the steps of receiving a primary print job and processing the primary print job with a primary processor to provide a plurality of primary pages to a print queue. The method further includes the steps receiving an interrupt print job and processing the interrupt print job with an interrupt processor to provide at least one interrupt page. The method further includes the step of printing the at least one interrupt page prior to printing at least one primary page in the page queue.

International Classification:

G09C 3/08

US Classification:

380051000

Abstract:

An improved electrophotographic printer is provided for generating a security stamp in firmware, and printing that security stamp to create documents that have a visible and tactile logo that is automatically printed on each page of a print job. The firmware will automatically create the proper bitmap of the security logo for a page's print resolution and bit depth. Using a color laser printer, the security stamp can be printed using all of the process colors, such as CMYK, which would be rendered and printed at 400% toner coverage. This gives the security stamp a very dark visible appearance and a thick tactile texture. The security stamp can include an area for printing a serial number of the printer, and for printing a time and date stamp.

International Classification:

G06K 1500

US Classification:

364514

Abstract:

A printer having a print engine (13) and a bit map memory (12) including a number of page image areas (31) into which information to be printed is rasterized and from which information for the print engine is serialized. A digital processor (11) controlling the print engine is operable to reduce a page image area (31) to a modified page image area (37) based upon the highest and lowest addresses at which information has been written into the page image area. The digital processor (11) is also operable to begin rasterization of a new page image area when a sufficient amount of an existing page image area (41) has been serialized to make available the requisite bit map memory for the new page.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

G06K 1500

US Classification:

395114

Abstract:

A high speed printing system including a host computer, a printer controller and a print engine. The printing system can operate in a normal mode where a high level page description language is used to convey page information from the host computer to the printer controller. The system further permits rasterization of a page to be printed at the host computer and the downloading of rasterized page data to the printer controller in a form that the data can be directly serialized to the print engine.

International Classification:

G06H 1500

US Classification:

395115

Abstract:

An improved printer is provided that receives a print job from a host computer and divides the bitmap image of a page to be printed into a series of image blocks or tiles. Each image block containing non-null data will be stored in the printer's memory system, typically placed in a non-contiguous memory location with respect to other blocks. The null image data blocks will not be stored in the printer's memory system, but instead only their locations on the physical printed page will be stored in a "block list table. " Each entry in the block list table contains the beginning address of the physical RAM area that contains one of the image data blocks, and also contains other variables or attributes concerning the particular image data block, such as whether or not this block is a regular non-null data block, or a "no-op" (or "NOP") block containing null data. Null data blocks require no physical memory address to be listed in their entry on the block list table, since no physical RAM areas are needed for storing null bitmap image data. Rather than building a band buffer in contiguous memory before shipping rasterized data to the laser printhead, the present invention builds in a cache a series of rasterized line segments of bitmap data in real time and sends them to the laser printhead "on the fly," by retrieving a single rasterized line segment of data, block-by-block, as needed to complete a single entire line.
